If that should ever change, it will be clearly indicated and opt-out will be available. We collect data in order to present anonymized statistics but do NOT send it outside or to your ISP. We do not have an interest in making ISPs look good! All test servers are located OUTSIDE your ISP in amazon and google data centers, the same ones that netflix and youtube use.Members can delete their tests and the data is actually, really, gone. Your entire test history is kept for your use even if you are not a registered member.Wide range of operating conditions: tuned to work accurately over proxy driven satellite links, over laggy phone links - yet in the same 30s to 60s run time it will also measure gigabit capable connections.The test works consistently as possible across all modern browsers: Kindles, Playstation4, SmartTVs, Linux, iPhones, Android, FreeBSD and more run the test daily.All your results, from any device, are together. This test does not require highly insecure and annoying (update? again!?) Flash plug-ins or Java installs, nor does it require installation of an app.Of course if you want single stream testing you can set that option in the handy preferences panel.

It also represents the modern usage pattern: someone is streaming netflix, a console is downloading a game patch, a VOIP or Skype call is taking place. Multi-stream testing overcomes the need for the speed test server to be physically very close to your location.

Speeds are quoted in megabits per second (1 million bits per second) or kilobits per second (1000 bits per second) of data. The test should take no longer than one minute to complete. It does a multiple stream download and upload to servers it determines may be closest to your location. A speed test checks the maximum speed of your connection to a remote server on the internet.
